March was the French cuisine month, but as usual, I wasn’t able to write and post all the recipes I made, so we’ll enter with some French recipes in April as well. By the way, April is dedicated to Italian food, so stay tuned, I have some really amazing recipes prepared for you! 🙂

Cassoulet is a popular French recipe made typically with sausages, pork skin, white beans, spices and some other veggies. It is basically a meat and beans casserole/stew.

Cassoulet is actually the name of the cooking dish in which this recipe is traditionally made. The recipe originates from the Languedoc region which is the home of Toulouse, Carcassone and other well-known French towns.

Cassoulets are also popular in the USA but you may simply know them as hearty bean-based casseroles. There are also variations, like salmon cassoulet.

There is actually a cassoulet version even in East European countries. For example, here in Romania, we have a very popular recipe called “fasole cu carnati” or “fasole cu afumatura” which is basically the same as cassoulet, beans and sausages or beans and smoked bacon.

So here’s my version of vegetarian cassoulet. I was too lazy to make the vegan sausages as well, but if you don’t mind spending some extra time in the kitchen and want to get this dish absolutely perfect, make these vegan minced “meat” rolls and simply add them to the vegetarian cassoulet.

I love everything about this hearty, slow-cooked white bean casserole recipe – the texture, flavors, everything blends so perfectly together. It is also perfect for meal prep, so make this awesome white bean stew on Sunday, or on your designated meal prep day, and you’ll have enough food for 5-7 days worth of lunches or dinners.

Enjoy! Don’t forget to drop me a comment and tell me how it was. I really appreciate your feedback!

  • 3 garlic cloves, minced
  • 2 medium carrots, sliced
  • 2 celery sticks, diced
  • 120ml (½ cup) dry white wine

Can you substitute canned beans for dry beans if no time to soak overnight?
